Many simple cardinal invariants

For g < f in ω we define c(f, g) be the least number of uniform trees with g-splitting needed to cover a uniform tree with f -splitting. We show that we can simultaneously force א1 many different values for different functions (f, g). In the language of [Blass]: There may be א1 many distinct uniform Π1 characteristics. 0. Introduction [Blass] defined a classification of certain cardinal invaria...
